It's based on data. ... Lower student to teacher ratios imply an improved environment for instruction That's a logical inference, but certainly not data. And sometimes what intuitively seems true winds up wrong. I challenge you to show empirical evidence that smaller class size improves educational outcomes. As I mentioned elsewhere in this thread, I've only ever found one such conclusive study, and that was only applicable to kids from lower-income families; in particular, no advantage was observed for average and above-average kids. And even for the slice of the population that might be helped (according to that study), we've got no evidence that these decreases in class size are occurring in schools having those students, as opposed to, say, more affluent schools that are presumably (there I go making an assumption) better able to afford more teachers.
